House purchase - problems with the transaction - experiences, tips?

but he wouldn’t be the first investor who has no plan.

*ahem*

Make a preliminary contract for the sale, in which both parties already commit to completing the sale in October 19, otherwise a contractual penalty of xx,xxx€ if one party no longer wants to proceed. Check with a lawyer if it is as simple as I imagine.

2000€ are (as already written several times) gone. The tenant has fulfilled his part of the agreement, so he is allowed to keep the money.

If you listen to the offer as an outsider, it might seem like a very good idea.
But if you know him as a person, then you approach it with caution.

How could something like that be made BINDING?
Who do I have to turn to for that? Tax advisor? Lawyer? Notary?

My bank advisor said I could make a land charge registration.
That would give me 100% security that he can no longer do anything... who is familiar with that?
